Claude Skills by Proact0

Designs Act and Cast architectures through dynamic questioning, outputting validated CLAUDE.md with mermaid diagrams. Use when starting new Act project, adding cast, planning architecture, extracting sub-cast (10+ nodes), or ask "design architecture", "plan cast", "create CLAUDE.md".

Implements LangGraph cast components following systematic workflow (state, deps, nodes, conditions, graph). Use when implementing cast, building nodes/agents/tools, need LangGraph patterns (memory, retry, guardrails, vector stores), or ask "implement cast", "build graph", "add node".

Guides pytest test writing for LangGraph casts with mocking patterns for LLM/API/Store calls. Use when writing tests, need mock strategies, setting up fixtures, testing nodes/graphs, or ask "write tests", "mock LLM", "test coverage".
